Application filed August 15, 1906. Serial No. 330,783.

T 0 all 107mm it may concern:

Be it known that I, PIERRE (JnioN, u citizen ol' the Republic of France,residing at 9 Rue (.lastex, Paris, France, have invented certainImprovements in Ap )aratus for (harging (a sulcs with Liquched Gas, ofwhich the fol owing is a full, clear, and exact description, and forwhich I have applied for Letters Patent in France, dated August 25,1905, (not issued).

T his invention relates to an apparatus which permits of decanting li'uefied gas instantaneously and automatical y from a large vessel, suchas a cylinder of liquefied carbonic gas, into a small vessel, such as acapsule, without loss of gas, or pressure, and without an intermediatecom rossor device. The apparatus also permits oFthe expulsion of any-airwhich may be contained therein before use or in the small vessels beforethey are charged.

The cylinders of liquefied carbonic acid gas to which this ap aratus isparticularly adapted, contain the iquefied gas at a pressure varyingwith the atmospheric temperature but generally exceeding atmosheres. Atthis pressure the gas has not cen utilized directly for its customarypurposes such as for drawing beer, the saturation of liquids, themanufacture of soda water and so forth; but has been drawn from thecylinder through appliances known as pressure reducers which reduce thepressure of the gas to such an extent that the liquelied gas returnsagain to its gaseous state.

Herotuforc if it has been desired to decent the contents of a largecylinder of liquefied carbonic acid into another container of smallerdimensions, at the same time maintaining in the latter a pressure atleast equal to that in the former, no means were known other than theuse of an intermediate compressor or pump which received the expanded asfrom the pressure reducer and T the same re-compressed. This hasheretofore been the customary Way of charging the small capsules orbulbs con taimng a few grams of ii uid carbonic acid by which siphons orse zogenos of a type now common, may be aerated. When a capsule has beenemptied, it has been returned for recharging, and it has been necessaryfor this iurpose to send it to a central factory provided with all thenecessary re;- charrog appliances. Obviously it would be high yadvantageous if this empty capsule could be re-charged on the spot,since liquid carbonic acid cylinders are obtainable everywhere. It wouldhowever, be impracticable to install com ressors or mechanical umps inthe esta lishments of all retail dea ers 1n siphons and ca sules.

The present invention provi es a hand appliance by which capsules may becharged directly from the cylinder of liquefied gas.

An apparatus embodying my invention is shown in the accompanyingdrawings, in which, 7

F igure 1 represents the general installation of the apparatus and thecylinder of ii uid carbonic acid for chargin small capsu es. Fig. 2 is avertical sectiona elevation of the apparatus pro erly socalled, andshows a capsule ready or charging. Fig. 3 is a vertical section at rightangles to the foregoing. Fig. 4 represents a vertical section slmilar toFig. 2, but in which the operative parts of the apparatus are shown inthe position which they occupy at the moment at which the capsule isbeing charged.

The cylinder a containing the li uefied gas is fixed upon a beam 1) or avertica wall, the said cylinder being inverted, that is to say itsaperture is arranged downwards, and this aperture is provided with thevalve head 0 sup lied with the cylinder. A pressure gage is screwed tothe head a and next to this pressure gage, which indicates the pres sureof the gas in the cylinder (1, the charging apparatus forming the objectof the present invention, is fixed.

This apparatus comprises a receptacle 0 in the 11 per part of whichthere is screwed a cap j raving a chamber g into which a passage Itopens; a hand screw maintains. a valve 11 on this assage. The passage 7icommunicatcs wit 1 the receptacle e and the chamber 9 is incommunication with the atmosphere by means of a small passage 1.: (Figs.1 and 3). The receptacle 0 comprises a socket I connected by means of anut in with the socket of the pressure gage d. To the lower part of therece )taclc 8 there is screwed a part n in which t ere is formed aassagc 0 which isclosed by a valve p hold y a spiral spring g bearing onthe one hand against the valve and on the other against tho licadf, Thereceptacle is prolonged by a tubular part r cut away at s andterminating in c. l orh if in which there is journalcd a cam 1.1 adaptedto ill oieratcd y hand by means of a handle ii. [.lpou the part 7' therevided with a seat for the mouth of a valved 1 capsule, means to carrythe capsule, means to press the same against said seat and means to openthe assage from the said container to said capsu e so as to permit thefiow of the liquefied gas into said capsule, substantially as described.

Apparatus for decanting li ueficd gas from a container into a receptac etherefor, comprising a passage communicating with said container belowthe level of the liquefied gas therein, provided with a discharge valveand a seat for the mouth of a rece tacle to he charged, means forpressing the atter to said seat, and means for opening said valve whilesaid receptacle is so seated whereby the liquefied gas will flow underits own pressure from said container into said receptacle to be charged,substantially as described.

4. Apparatus for decanting liquefied gas from a container into areceptacle to be charged and adapted to be carried by said container,comprising a discharge passage 0 enmg into said container below thelevel oFthe liquid therein and provided with a discharge valve, acarrier for a rece tacle to be l charged from said container am meansfor bringing said receptacle into communication l with said dischargepassage and means for time, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
